The MU Lab develops tools for studies of resolved stellar populations in the Milky Way, microlensing, orbits, and high-precision astrometry from space-based telescopes and with adaptive optics on ground-based telescopes. Some of our tools are listed below.

SPISEA - Stellar Population Interface for Stellar Evolution and Atmospheres
SPISEA (docs) is an python package that generates single-age, single-metallicity populations (i.e. star clusters). It gives the user control over many parameters:
Cluster characteristics (age, metallicity, mass, distance)
Total extinction, differential extinction, and extinction law
Stellar evolution and atmosphere models
Stellar multiplicity and Initial Mass Function
Initial-Final Mass Relation
Photometric filters
Here is a brief list of things that PyPopStar can do:
make a cluster isochrone in many filters using different stellar models
make a star cluster at any age with an unusual IMF and unresolved multiplicity
make a spectrum of a star cluster in integrated light
PopSyCLE

- Population Synthesis for Compact-object Lensing Events
...
PopSyCLE is a python add-on to the Galaxia modeling code that will make a fake Milky Way populated with stars, white dwarfs, neutron stars, and black holes. The synthetic population can be “observed” for microlensing events.

NIRC2 and OSIRIS Image Reduction Pipeline
NIRC2/OSIRIS Imager Pipeline (request access) is a python-based (with IRAF dependencies) data reduction pipeline for the NIRC2 and OSIRIS adaptive optics imagers at the W. M. Keck Observatory. This pipeline was built to construct images of star fields to be used for high-precision photometry and astrometry. It does typical image reduction tasks as well as correcting for differential atmospheric refraction, instrumental distortions, and unique instrumental aspects of each instrument (e.g. noisy columns in NIRC2). When combined with StarFinder or AIROPA, this pipeline will also extract positions and fluxes from the images. The code is currently not public (but may be used upon request) as it has dependencies on a number of other non-public codes.
FlyStar
FlyStar is a tool for cross-matching and transforming starlists for high-precision astrometry projects. It is currently under development and alpha-testing.
